Abstract

　ＡＶＣ符号化方式に基づく画像圧縮情報を出力する画像情報符号化装置において、階層Ｂピクチャで構成されるＧＯＰ構造における最適な参照関係及び瞬時復号器更新ピクチャでないＩピクチャからのランダムアクセスを可能にする。 　マルチプルフレーム予測を行う際に、メモリ管理制御コマンド発生部（１３）により、復号画像バッファ内のピクチャを管理するメモリ管理制御コマンドを用いて、ＰピクチャもしくはＩピクチャの間にある参照Ｂピクチャを長期間参照ピクチャに登録し、ＰピクチャもしくはＩピクチャと参照Ｂピクチャの間にあるＢピクチャにおいて参照画像リスト順序コマンドを用いて参照Ｂピクチャを参照画像リストの最初に配置し、メモリ管理制御コマンドにより、ＰピクチャもしくはＩピクチャで長期間フレームインデックスの最大値を［０］に設定することにより、復号画像バッファ内の長期間参照ピクチャを非参照ピクチャに設定し、瞬時復号器更新ピクチャでないＩピクチャからのランダムアクセスを行う。
